Device for synchronous opening-or-closing movement of cabinet&#39;s cupboards

ABSTRACT

The present invention relates to device for synchronous opening-or-closing movement of cabinet&#39;s cupboards which mainly includes a major cupboard and two minor cupboards. The major cupboard is pivotably fitted to the center of the cabinet by means of a first hinge for turning at 180° at the original place. Both of the minor cupboards are pivotably fitted to each side of the cabinet by means of second hinges, respectively, for turning at 90° at the original place. The first hinge is provided at top of the major cupboard and is pivotably connected with two connecting rods at each side thereof. The other end of each of the connecting rods is pivotably connected to a turning point at top of the respective minor cupboards  30.  When the major cupboard or the minor cupboards are turned at the original place, the other one will be brought into a synchronous opening-or-closing movement.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a device for synchronous opening-or-closing movement of cabinet's cupboards, and more particularly, to a device which brings the other cupboards in synchronous opening-or-closing movement when one is moved to open or close.

[0003] 2. Description of the Prior Art

[0004] In order to store and sort various objects, it's common that the cabinet is divided into minor cupboards or cases with drawers, shelves, etc. In searching for one object, each cupboard or case has to be individually opened until the searched object is found. It's much troublesome.

[0005] It's similar to the display cabinet for commercial use. Many chances would be lost in opening and closing cupboards or cases one after another for showing the customers different products who would be impatient for these repetitive actions.

SUMMARY OF THE INVENTION

[0006] It is a primary object of the present invention to remove the above-mentioned drawbacks and to provide a device for synchronous opening-or-closing movement of cabinet's cupboards in order to store and take objects more efficiently.

BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The accomplishment of this and other objects of the invention will become apparent from the following description and its accompanying drawings of which:

[0008]FIG. 1 is a perspective view of a preferred embodiment of the present invention;

[0009]FIG. 2 is a schematic drawing of the device in accordance with the present invention for synchronous opening-or-closing movement of cabinet's cupboards;

[0010]FIG. 3 is a schematic drawing of the device in accordance with the present invention for synchronous opening-or-closing movement of cabinet's cupboards, showing the action thereof; and

[0011]FIG. 4 is a developed view in accordance with FIG. 1.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0012] First of all, referring to FIGS. 1 through 3, a preferred embodiment of the present invention mainly includes a cabinet 10 in which much room is existing for pivotably mounting a major cupboard 20 and two minor cupboards 30. The major cupboard 20 is pivotably fitted to the center of the cabinet 10 by means of a first hinge 22 for turning at 180° at the original place. Both of the minor cupboards 30 are pivotably fitted to each side of the cabinet 10 by means of second hinges 22, respectively, for turning at 90° at the original place.

[0013] The first hinge 22 is provided at top of the major cupboard 20 and is pivotably connected with two connecting rods 40 at each side thereof. The other end 42 of each of the connecting rods 40 is pivotably connected to a turning point 34 at top of the respective minor cupboards 30. When the major cupboard 20 or the minor cupboards 30 are turned at the original place, the other one will be brought into a synchronous opening-or-closing movement.

[0014] When the major cupboard 20 or the minor cupboards 30 are not opened, it's identical to the common one (see FIG. 1). When the major cupboard 20 or the minor cupboards 30 are synchronously opened, they will be developed as shown in FIG. 4 for achieving the expected convenience and effect.

[0015] The connecting rods 40 can also be fitted to the bottom of the major and minor cupboards 20 with the same functions.

[0016] Many changes and modifications in the above-described embodiment of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claim. 

What is claimed is:
 1. A device for synchronous opening-or-closing movement of cabinet's cupboards comprising: a major cupboard pivotably fitted to the center of said cabinet by means of a first hinge for turning at 180° at the original place; and two minor cupboards pivotably fitted to each side of said cabinet by means of second hinges, respectively, for turning at 90° at the original place; wherein said first hinge is provided at top of said major cupboard and is pivotably connected with two connecting rods at each side thereof; and wherein the other end of each of said connecting rods is pivotably connected to a turning point at top of said respective minor cupboards so that, when said major cupboard or said minor cupboards are turned at the original place, the other one will be brought into a synchronous opening-or-closing movement.
 2. The device for synchronous opening-or-closing movement of cabinet's cupboards as recited in claim 1 wherein said connecting rods are fitted to the bottom of said major and minor cupboards.
